New complexes of Cd(II), Zn(II) and Ni(II) with 2-quinolinecarboxaldehyde selenosemicarbazone (Hqasesc) were synthesized and structurally characterized. The structure of the ligand, Cd(II) and Zn(II) complexes was determined by NMR and IR spectroscopy, elemental microanalysis and molar conductivity measurements. Both complexes occur in solution in two forms, the major tetrahedral and minor octahedral...
A novel ligand 2,6-diacetylpyridine-bis(selenosemicarbazone) was synthesized and coordinated with Zn(II), Cd(II) and Ni(II). With Zn(II) and Cd(II), the bideprotonated ligand was coordinated as a quinquedentate in trigonal bipyramidal geometry. With Ni(II) during coordination the ligand was modified by elimination of hydrogen selenide and the product was coordinated as a quadridentate forming a square...
